Clinical Testing for Golfer's Elbow (Medial Epicondylitis)
The primary clinical test for diagnosing golfer's elbow involves palpating the medial epicondyle for tenderness and performing resisted wrist flexion and forearm pronation, which reproduces pain at the common flexor tendon origin on the medial epicondyle.
Clinical Presentation and Diagnosis
Golfer's elbow (medial epicondylitis) is a tendinopathy affecting the common flexor tendon origin at the medial epicondyle, occurring in 1-3% of the general population and presenting most commonly in patients aged 40-60 years 1, 2, 3. The condition affects both men and women equally and results from repetitive wrist flexion and forearm pronation activities 4, 5.
Physical Examination Technique
The diagnostic approach centers on specific provocative maneuvers:
Point tenderness over the medial epicondyle is the hallmark finding, typically located at the common flexor tendon origin approximately 4-10 mm anterior to the posterior ridge of the medial epicondyle 6, 2
Resisted wrist flexion test: Pain is elicited when the patient flexes the wrist against resistance while the elbow is extended 2
Resisted forearm pronation test: Pain occurs with resisted pronation of the forearm, as this stresses the pronator teres and other flexor-pronator muscles 5, 2
Pain with passive wrist extension: Stretching the flexor tendons by passively extending the wrist can reproduce symptoms 2
Differential Diagnosis Considerations
Critical to avoid misdiagnosis, you must distinguish medial epicondylitis from:
Ulnar collateral ligament (UCL) injury: The UCL originates approximately 10.4 mm from the posterior ridge of the medial epicondyle, posterior to the common flexor origin 6. Valgus stress testing helps differentiate this condition 7
Cubital tunnel syndrome: Assess for ulnar nerve symptoms including numbness/tingling in the ring and small fingers, and perform Tinel's sign at the cubital tunnel 1, 7
Snapping triceps syndrome: Dynamic ultrasound can identify medial triceps subluxation 7
Imaging Considerations
While diagnosis is primarily clinical, imaging may be warranted:
Radiographs are the initial imaging modality for chronic elbow pain to exclude osseous pathology, heterotopic ossification, or calcifications 1
Ultrasound has 95% sensitivity and 92% specificity for confirming medial epicondylitis and can visualize tendon thickening, hypoechogenicity, and neovascularity 7
MRI is not routinely indicated for initial evaluation but may be useful if diagnosis remains uncertain or surgical planning is needed 1
Clinical Pearls
A key pitfall is confusing medial epicondylitis with UCL injury, particularly in overhead throwing athletes 5. The UCL lies more posterior and inferior on the medial epicondyle compared to the common flexor origin 6. Valgus stress testing will be positive with UCL pathology but negative with isolated medial epicondylitis 7.
The condition is less common than lateral epicondylitis (tennis elbow), occurring at a ratio of approximately 1:7 to 1:10 4. It predominantly affects the dominant arm in athletes who throw, golf, or perform repetitive forearm pronation and wrist flexion 5, 3.
